The present invention relates to the technical field of
waste gas treatment devices, and discloses a
waste gas treatment device for herbicide production, including a shell cover and a filter
cartridge, wherein a rotary disk is rotatably connected to the inner side of the shell cover, and a
water storage tank is fixedly arranged at the bottom of the rotary disk; a
slip ring is slidably penetrated in the shell cover, and a linkage component and a transmission component are arranged on the inner side of the shell cover; a drainage groove is formed at the bottom of the
water storage tank, a rotary opening and closing component is arranged at the bottom of the
water storage tank, and a
water delivery port is formed in the shell cover. In the present invention, firstly, by directly rotating and replacing the
water storage tank that has reached a saturated state, it is beneficial for the device to continuously and efficiently treat the
waste gas, thereby achieving the purpose of improving the waste gas treatment efficiency; secondly, when the
slip ring is pressed into the vent, the downward port of the
slip ring is in
close contact with the
retaining ring, and the circular ring of the upward port of the slip ring is in
close contact with the top end face of the shell cover, thereby preventing the waste gas from being directly discharged to the outside without being irradiated by an
ultraviolet lamp and the action of a filter, thereby ensuring the
treatment effect of the waste gas.
